Be it known that I, WADE a citizen of the United States of America, and a resident of Huntington, county of Cabell, State of West Virginia, have invented certain new and useful Improvements in W indow-Scaffolds, of which the following is a full and clear specification.

The object of this invention is to provide a light and simply constructed scaffold or balcony which is adapted to be readily put in position on the window frame and readily detached therefrom, as more fully hereinafter set forth.

In the drawings-Figure 1 is a vertical sectional view of my device applied to a window; Fig. 2 a vertical sectional view on the line 22 of Fig. 1; Fig. 3 a horizontal sectional view on the line 3-3 of Fig. 1; Fig. 4 an inside view of a window frame showing my device applied thereto; and Fig. 5 a detail sectional view of one of the window sill clamp members.

My device consists of a balcony proper made up of transverse bars a bent up at their ends to form upright side bars I), the upper ends of these side bars being connected by a longitudinal side bar 0. The outer end of the balcony is closed by horizontal bars cl and by vertical bars 6. The bottom of the balcony consists of the aforesaid transverse bars a, long horizontal bars 7 and short horizontal bars 9, these latter being continuations of two intermediate bars 6 and being riveted at their inner ends to the nearest cross bar a. A transverse bar 7b connects the extreme inner ends of the long bars 7 and forms the inner edge of the balcony, which edge is adapted to rest upon the outer edge of the window sill. In addition to the bars a, g and h, the floor of the balcony consists of two longitudinal bars '5 which are in alinement with the short bars 9 and extend beyond the inner edge of the balcony. These bars i lie upon the cross bars a and h and are adjustably secured to the bars a by means of slots 9' formed in the bars 2' and bolts 70 passed down through said slots and connected to the bars a. The extreme inner ends of the bars i are bent downwardly to form hooks Z which depend behind the inner edge of the window sill. Attached to the under side of the bars f are stop braces consisting of a depending bar we and a diagonal brace n. p

Specification of Letters Patent. I Patented Jan; 25, 1916;

' hooks "Z are engaged, as stated,*' down -over '-the"1n'ner edge of the window s1ll and the bars 2' are adjusted so as to bring the stop members at up against the outer edge of the window sill and thus form a sort of clamp for engaging the window sill. Bars 2', it will be seen, not only perform the function of clamping members, but also constitute part of the floor or bottom of the balcony, this being an important feature of my de vice. To hold the balcony in position against tilting downwardly and outwardly, I employtwo pairs of stay rods, one pair 0, arranged in the lower corners of the balcony, connecting at their outer ends to the outer vertical bars 6 and at their inner ends to cross bar p which is clamped against the inner edges of the vertical members of the window frame by means of nuts 9 threaded on to the extreme inner ends of the stay rods. The other pair of stay rods 0 have their outer ends connected to the extended upper ends of the two middle bars 6 and extend upwardly in a diagonal direction to the upper end of the window frame, where they are connected to a bar 8 similar to bar 39 and in the same manner. With these two sets of stay rods, it will be seen that the balcony will be securely suspended, the nuts on the ends of the stay rods serving to draw them taut and thus clamp the bars 19 ands against the window frame. Each of the stay rods is preferably made, as shown, in two sections connected together midway the length of the stay rod by interlocking eyes 6, to give flexibility to the stay rods.

In erecting the scaffold, the lower cross bar p is easily held in position as it rests upon the ends of the bars 2', but the upper bar 8 requires means for holding it in position, at least temporarily, during the work of erecting the scaffold. To thus hold this bar 8 in position, I pivotally attach to its inner face a pair of hooks to long enough to engage over upon the upper projecting edge of the window frame, these hooks being preferably provided with downwardlyturned short, sharp points 4) to prevent them sliding off the edge of the window frame.

Having thus described my invention, what I claim is:

The combination with a balcony and means thereon for engaging the window sill, of a suspending means embodying two pairs of stay rods connected at their outer endsto the outer end of the balcony, one means for tensioning the stay rods, and pair extending to the upper part of the Winhooks attached to the upper one of said bars 10 dow frame and the other pair extending difor detachable engagement with the inrectly inwardly to the lower end of the Winwardly-projecting upper edge of the- Win 5 doW frame, a cross bar in engagement With dow'irame.

the inner ends of each pair of stay rods and In testimony whereof I hereunto afiix my adapted to-lie against the inner edges of signature. 1 V the vertical members ofthe Window frame, I V VADE WASHINGTON.
